SERVICE INFORMATION
Intelligent Key systems on the Applied Vehicles use two (2) different Radio Frequencies
(RF) that are similar to other wireless devices; 315 MHz and 433 MHz.
In the event another wireless device (e.g. aftermarket alarm system) is transmitting at the
same time as an Intelligent Key, it can interfere with the Intelligent Key signals being
received by the BCM.
If there is interference with Intelligent Key signals, the following symptoms may
occur:
 The Intelligent Key is not detected, causing:
 The engine to not start (no response when the Stop/Start button is pressed)
 “I-Key System Error” displayed in the instrument cluster
 “No I-Key Detected” displayed in the instrument cluster
 Intermittent operation of the buttons on the remote (Key FOB).
 Intermittent operation of the door request switches.
The above symptoms are usually intermittent and can be difficult to diagnose.
If a vehicle has experienced the above symptoms, or a customer has reported the above
symptoms, refer to Supplemental Diagnosis / Information on the next page.
Nissan Bulletins are intended for use by qualified technicians, not 'do-it-yourselfers'. Qualified technicians are
properly trained individuals who have the equipment, tools, safety instruction, and know-how to do a job properly
and safely. NOTE: If you believe that a described condition may apply to a particular vehicle, DO NOT assume that
it does. See your Nissan dealer to determine if this applies to your vehicle.

NOTE:

The diagnostic items listed below should be checked before replacing any parts or
performing any repairs.

Refer to the appropriate Electronic Service Manual (ESM) for complete Intelligent
Key system diagnosis and repair information.
Supplemental Diagnosis / Information

Intelligent Key fob battery check:
 Use Signal Tech II IKEY Battery Test to confirm battery state of charge.

Location of Intelligent Key: An Intelligent Key should not be stored where the RF
signal can be obstructed by nearby metal objects.

Interference from other personal devices: Confirm the Intelligent Key is not placed in
close proximity to phones, other Intelligent Keys, highway PASS Card, USB charger,
Personal Computer (PC) charger, etc. that may be transmitting similar RF signals.
 Technician should remove all devices from vehicle while diagnosing/duplicating
the customer issue.
Example of electrical
device that can cause
interference
Figure 1

If none of the above are causing symptoms, check the following:

Inspect the vehicle for the presence of an aftermarket alarm system or radar
detector.
NOTE: RF signals coming from the vehicle surroundings can interfere with the
Intelligent Key signals (e.g. radar detectors or aftermarket alarm systems in
other vehicles, or RF signals from surrounding buildings).
